Most countries that ban bitcoin are against privacy and decentralization and lack control. Centralized coins like Ethereum aren't really threats to their financial institutions.
Besides even if you clone it surely it wouldn't be 1:1 ratio .
So why not jump into another alt-coin.
People would love to keep on their bitcoins that of altcoins because of its profitability and being accepted in the market and so they'll do anything to makes used of them.
Good thing it won't happen in our country and we are able to use bitcoin or any crypto's freely and don't have any struggles.
I mean look at China even, a conviction rate of 99.99, you think these countries give a shit if it's a clone?
